rlhe present invention relates to the forming andfolding of alimentary pastes such as spaghetti, noodles, vermicelli, andthe like,

and is more particularly directed to a method 5 of and a machine for making spaghetti out of dough and forming it into bundles or units suitable for handling and use. As ordinarily V,prepared spaghetti comes from the machine yin the form Vof long thin threads of dough which must later ybe dried.

The present invention contemplates an 1mproved method of and means for handling these threads so as to assemble a number of them into bundles,havingpreferably a conis figuration'substantially like a figure 8. Ac-

cordingly, a number of threads of dough (suitable to form a bundle) is picked up in y i the middle and allowed to hang downwardly.

It is gradually lowered intoa receiving tray to which the-ends of the strings adhere slightly and the support for the doubled threads is given` an irregular horizontal movement so that the bundle deposited on the tray has the desired configuration. Vhile this method 25 may be carried out by hand, it is preferable to carry it out by machine, and an object of the invention is, therefore, vto provide a spaghetti forming and folding -machine which maybe operated by power to form the spaghetti into bundles.

Another objectof the Vinvention is to provide a folding device which acts on -a plurality of bunches of strips of dough-at the same time` thereby making a number of twisted bundles of spaghetti simultaneously.

Another objectof the invention is to vprovide a spaghetti forming machine-with a reciprocatory carriage provided with 'troughs adapted to receive and assemble the spaghetti into bunches of a size suitable for handling.

Another object of the invention is to provide a spaghetti forming and folding machine with a tray for the folded bundles of 'spaghetti and means for advancing the tray. lli Another object of the invention is to provide a mechanically operated finger, which) may be brought under a bunch of spaghetti to lift it and transfer it to a trayv and at vthe saine time move the bunch in such a manner 1e tion ratherthan limiting the sama that it is 'twistedilbo acompactbundlapreferablv shaped like afigure. The invention contemplates that the finger-be cam-operated,

the present Iinvention may be embodied, and .the `carrying out of the method, are shown ,for purposes of illustration, in the accompanying drawings, 1t 'being understood that these drawingsaY illustrative of the inven- Inthese drawings; y

The machine may be driven from-any suitable source of power through a pulley 10 carriedin `the upper rear portion of a suitable frame `11. A pinion 12, carried on the pulley shaft meshes with a gear 13 which drives a shaft 14. lThis sha-ft 14: carries a gear '15 which meshes with a gear 1'6 carried on a shaft 17, above ,the shaft '14. Thesek two shafts carry'fcooperative squeeze vrolls (notshown), e5 which `operate on dough to squeeze or roll it intoa thinsheet A ,and pass it out in the direction of the arrows. The thinness of the Vsheet of dough is under the control of the ,operator adjusting `the squeeze rolls 10@ Y The driving connections for the slitting or stripping rollers, 2O and 21, utilize a chain 22 driven from a sprocket wheelon shaft 14. This chain drives a sprocket wheel 23 carried on shaft 24 extending across the frame; and this shaft carries a gear 25, see Fig. 1, which meshes with a gear 26 carried on a shaft 27. This shaft 27 carries a sprocket gear 28, driving a sprocket chain 29, which operates a gear 30 near the stripping rollers. This gear 30 drives the stripping or slitting roller through gears 31, 32, and 33.

As the strips or threads B hang from the rollers 2O and 21, they are directed'into a chute 34 carried above a-rotary cutter 35. This cutter is carried onashaft 36 driven through a sprocket chain 37, which is operated by a-sprocket wheel 38 carriedv on the shaft 24. In order that the hanging threads may be separated from one another Vso as to facilitate the forming of bunches of spaghetti, thereis preferably provided a loose roller 39 placed in the trough, and provided with cones 39 as shown in Fig. 5.

Underneath the cutter the machine is provided with'a reciprocatory carriage 40 to receive the cut threads of spaghetti. The upper surface of this carriage is preferably provided with ,a number of llongitudinal troughs 41, which may conveniently be made by providing raised portions or ridges 42. The carriage rides on supports 43 and 44 carried by frame 11. It is operated by a pitman 45 pivoted at 46 in the upper part ofthe frame and provided with a lost-motion pinand-slot connection 47-48 with thecarriage. This pitman is connected by a system Aof links 49, with a follower 50, placed in a cam track 51 onv a cam 52. This cam member is carried on a shaft53, and is driven by means of a sprocket chain 54, operatably connected with the shaft 24 The freshly formed spaghetti is deposited in the troughs 41, in the form of a number of rows or bunches. The neXt step is to transfer this spaghetti into a receiving surface and fold or twist it into the desired formso as tochange each bunch of loose threads into a bundle suitable for drying andfurther handling. Suitable mechanism for carrying out this operationis illustrated at -the front or righthand part of Fig. 1 and in Figs. 2, 4, 6, 7 and 8, 1 K

A frame 55 is suitably supported in front of the frame 11. Near the top of this frame there is mounted a shaft 56, which is driven by means of a sprocket chain 57, cooperating with sprocket wheels 58 and 59. The latter sprocket wheel is mounted on the back side of the frame 11, and is driven from the shafL 24 through suitable gears 24 and 59. This shaft 56 drives, through sprocket chain 60, the shaft 61, carried in the frame members 55 and 55 underneath the shaft 56. These two shafts are interconnected with and operate a number of folding fingers 62 through a number of cams and links. These fingers are actuated so as to pick up the bunches of spaghetti which rest on the carriage and deposit them on the receiving tray.

This tray is here shownin the form of a vlong box 63, provided with a screen 64 and carried between guides 65 and 66. It rests on sprocket chains 67, driven through sprocket wheels 68, which are actuated in an intermittent fashion through a pawl 69 and ratchet wheel 70. The pawl 69 is operated through a link 71, connected with the cam 52 at the left of the rear end ofthe machine.

This shaft 56 is provided with a pair of wide faced cams 72 which actuate followers 73 carried on a vertically reciprocable rod 74, springs 75 acting to keep the followers on the face of the cams. This rod is guided for vertical movement by being placed in slots 741 in vert-ical members 742. These members are carried from a fixed bar 743, above the shaft 56 which also passes through the slots. T ie rod' 74 carries a number of depending links 76 which are pivoted through swivel bolts 77 to depending links 78. The lower ends of these links are connected with the front ends 79 of curved arms 80 each of which carries a finger 62 at its outer free end. Thesevarms 80 are pivoted at 81 onto upstanding members v82, pivotally supported in a transverse bar 85.

The rotation of the cams 72 gives the free ends of the fingers 62 vertical movement. The vertical movement of each finger 62 is modified byother cam means which give it longitudinal and lateral movements. The longitudinal movement is imparted to the -finger'62 by means of cams 83 carried on the "and this carries the fingers 62 back and forth in a horizontal direction. Y

In order that the fingers 62 may have a lateral horizontal movement, a suitable arrangement is provided to rock all the fingers.

lclosing `thejaws which are'to 56. As the shaft 56 rotates the rod193 will be moved to the left or right, as shown in Fig. 4. This will cause the Jfollowers 73 to travel back and forth over :the face of the cams 72. VIt willshift the rod 74back and forth and this will cause'thelinks 7 Sto also move tothe right or left. This movement will cause the free ends 79 of the arms 80 to move to the right or left, and, as themembers 82 are pivotally con -nected to the transverse .bar 85, permitting the arms 80 to swing laterally, a sideways movement will be given to the fingers 62. v

Each finger 62- functions as part of a pair of :ja-ws which are caused to. descend down-A wardly past the bunch of spaghetti threads, and'to close so as ito .engage under the threads and carry `them.` over to the. folding' table. These jaws are to open at the proper time to release the folded or twisted bundle.

Each arm is provided with bearings 97 andl98, in which is pivotally mounted a shaft 99. The end ofthe shaft near the finger V62 lis ibentdownwardly inthe same Vmanner as the finger 62, and terminates along side of the sameQ The rear end of this shaft 99 is .con-

nected with a llink 101, which is in turn connected with ahorizontal transverse rod 102 supported for movement back and forth or .the roller 106 yieldably in engagement with the cam107. The other .end ofthe rod 102 is pivotally connected by the link 118 .to the support 119 extending from the frame `mem- `ber'55. As the shaft 56 rotates the Vrod 102 will be movedback and forth and will carry the links 101 with it, thereby turning the shafts 99 in theirl bearings, and opening and pick up and later release the spaghetti. v Y The movements, given to the jaws or fingers by the cam mechanisms which have been described, are such that all of the fingers move to the rear or left, and are lowered into a `transverse trough 108 in the `carrier 40. Thereupon the cam 107 operates theparts connected to it fto closethe jaws. The aws pick up the bunchof spaghetti, as indicated Vin Fio'. ,7, and the carriage 40 retreats. The v cams' 2 and 83 and 95 operate the links and fingers so as to move the finger in the three directions and at the proper time. Theyfirst lower the doubled bunch of spaghettiso that the lower ends touch the bottom of the receiving tray 63. Y The ends of the 4spaghetti usually stick or adhere-to the wire64.- When the lfinger is near thebottomof its movement, the 4cam and follower 107 and 106 `open the jaws andthe spaghetti is released. The receiving tray 63 is then advanced, and the operation is repeated. n ,Y Y

Whilethe finger is moved through` a path .of rather irregulary curvature, it mayfbelescribed, conveniently, (when viewed from above) as being in the form of a letter S during the first Y part of the lowering of the spaghetti. The movement .through another (inverted) S, soas to makea vunit in which the'strands are shapedsubst-antially `like a figure 8. The shape and sizeof these twists will depend Von the configuration of the cams.4 They may bevaried'consider-l ably and yet produce 4.a unit convenient :for drying and packing.

v In order toassist instraightening out 'the spaghetti,` as it hangs from, the fingers 62,

there is provideda reciprocatory bar 1.109 .i

which is 'carried in guides 1,10 andlll; This bar is pulled to the leftl by springs 112,and is moved `to .the right by means of .curved links 113 which `carry-followers 114, cooperating with the cams 115, carried on the shaft 56.: These curved links are ycarried `on the fixed bar 743 near the top ofthe frame.

While :the specification and claims refer `more,specicallygto the formingand folding of spaghetti, it is, of course, to lbe understood that the present machine and Lmethod are equally well adapted tof operate von .other forms of alimentary pastos, and on plastic materials in general; v`and it yisili-tended that the termk spaghetti used herein should .be vdescriptive ofsuch materials.
